Re: [web2py] Exception calling value in template that is not defined.

Strange this did not work.


But Bruno's solution did.

if 'form' in globals():
   {{= form }}

If you want to test specifically whether 'form' was returned in the dict of the controller action (as opposed to possibly being defined in a model file), you can also do:

{{if 'form' in response._vars:}}

        I want to be able to check if a key is there before I use it.

        Thanks.
